The aim of this study was to compare subjective (Ramsay sedation score, RSS) with objective electroencephalogram-based bispectral index (BIS) assessment, and to validate the appropriate BIS range for measurement of conscious sedation in interventional procedures. ⋯ BIS monitoring enables more effective titration of sedatives to maintain a suitable level of consciousness, whilst reducing procedure time. The BIS offers an objective, safe and reliable measure of sedation, without disturbing either patient or operator. BIS monitoring raises the standard of patient care, and in our view, should be used to augment standard assessment.

To corroborate the findings of in utero magnetic resonance imaging (MRI) with autopsy and post-mortem MRI in cases of known or suspected central nervous system (CNS) abnormalities on ultrasound and to compare the diagnostic accuracy of ante-natal ultrasound and in utero MRI. ⋯ In utero MRI provides a useful adjuvant to antenatal ultrasound when assessing CNS abnormalities by providing more accurate anatomical information. Post-mortem MRI assists the diagnosis of macroscopic structural abnormalities.

There is a wide variety of pathological processes which may present with swelling in the submandibular space. Although the submandibular gland is the most important structure in this region, there are a number of extraglandular causes of swelling which frequently mimic submandibular gland enlargement. In this review the use of high-resolution ultrasound in the assessment of the submandibular gland and adjacent structures is discussed and illustrated.
